• In the etch & rinse 3-step systems type I (4th generation) the total-etch technique is used, enamel and dentin are etched. Primer and bonding agent are included as separate liquids.
• The etch & rinse 2-step systems type II (5th generation) represents the combination of the last two steps of the 4th generation. Primer and bonding agent are available as one bottle. Processing is comparable to that of 4th generation systems with one step less.
• The self-etch 2-step systems type III (6th generation) includes self-conditioning primers resp. self-conditioning bonding agents to be mixed. The shortcomings of previous generations with regard to conditioning / wet-bonding / hybrid layer formation are to be eliminated.
• The self-etch 1-step systems type IV (7th generation) includes all-in-one bondings. Etching, priming and bonding are accomplished with only one bottle.

• The term total etch is used for simultaneous etching of enamel and dentin with e.g. phosphoric acid to remove the smear layer and to obtain micro-porosities for the integration of the bonding agent. The etching always starts with enamel and then dentin. Enamel is etched for 20s, dentin for 15s. Excessive etching can cause hypersensitivity and incomplete hybrid layers.
• The term “Total Etch” also stands particularly in the anglo-american countries as a synonym for 5th generation ( Etch & Rinse 2-step ) bondings. That was the reason to call our new product accordingly iBOND Total Etch.

• This term describes the fact that the exposed collagen fiber structure still contains some water and is not dried out completely after etching. Only excess water is removed by air blowing. The water in the intrafibrillary spaces remains and protects them to avoid collapse of the collagen fibers and a consequent reduction of penetration of applied adhesives.

• iBOND Total Etch is the new 5th generation Etch&Rinse 2-step ?(1-bottle) adhesive from Heraeus Kulzer with improved nano-based formula. iBOND Total Etch is the consequent further development of GLUMA CB & GLUMA CB + Desensitizer, that primes, bonds and desensitizes in only one single step by application of only one layer. ?Due to this it combines high bond strength, improved marginal sealing and desensitizing effect with a fast and convenient application.

• Similar to iBOND Self Etch, you get around 50 applications out of an iBOND Total Etch bottle.

• In general iBOND Total Etch can be stored outside the refrigerator ?(max. 25° C), but it is for sure possible to store iBOND Total Etch also in the refrigerator if this is prefered by the customer

• No, the iBOND Total Etch bottle has not to be shaken before use

• Just like any other bonding material, iBOND Total Etch contains solvents. Since iBOND Total Etch is ethanol-based the composition and the efficiency change when the material has been poured out of the bottle quite some time before (longer than 3 - 5 minutes). Close the bottle after use to avoid any evaporation of ethanol.

• 3 – 5 minutes.

• No, agitation is not required and not necessary

• Theoretical spoken – yes, less material is necessary, but usually customers use in general more drops, so that the savings of material, do not have practical relevance

• Yes, this is possible because using iBOND Total Etch is in both cases possible uncut and cut enamel. Because of the fact that the etching process is done separately before applying iBOND Total Etch on cut or uncut enamel.

• Yes, because the etching process in done separately any way, before applying iBOND Total Etch on sclerotic dentin.

• 20 seconds.

• Yes, ?iBOND Total Etch is compatible with LED. ?Use of LED needs 100% of recommended curing time ?(20 seconds)

• Yes. ?iBOND Total Etch contains all components. ?You can use any other applicator that is ethanol resistant.

iBOND Self Etch

• Adhesive layer: 3-5 µm
• Hybrid layer: 0.3-0.5 µm
• The hybrid layer of iBOND Self Etch corresponds to the demineralization depth

Total-Etch Systems

• Adhesive layer: 5-20 µm
• Hybrid layer: 1.5-3 µm
• Demineralization depth: 10-50 µm

• According to a study done by Prof. Haller, University of Ulm Germany, iBOND Total Etch received excellent results regarding staining marginal quality. In a comparision with Adper Scotchbond 1 XT, Excite and XP Bond, iBOND Total Etch was the top of class product in this matter.

• iBOND Total Etch needs to be applied in only one layer and the air drying of the layer is quite easily as the material remains stable in the cavity, there is no agitation necessary.

• The percentage of nano-fillers in iBOND Total Etch ?is between 1% - 5 %.

• iBOND Total Etch contains glutardialdehyde that close the dentin tubuli internally and operates in the same way than GLUMA Desensitizer.

• Desensitization of restorations is permanent just like with the pure desensitizer or GLUMA Comfort Bond + Desensitizer. Desensitization of non-filled tooth areas is maintained for 6 month to one year, depending on patient-specific erosion factors.

• Tooth surfaces treated with iBOND Total Etch do not have to be treated separately with desensitizers. Nevertheless a separately desensitization only with GLUMA Desensitizer is possible

• iBOND Total Etch can be used in combination with light and dual curing luting materials in case of indirect restorations.

• Yes. Only some µm of the calcium hydroxide surface will be slightly dissolved.

• Numerous studies recommend not to use the material for this purpose. Heraeus Kulzer does not recommend iBOND Total Etch for direct pulp capping. This should be done traditionally.

• A contamination check is essential. If this is ensured, the use of rubber dam may not be required in certain cases, decided by the dentist. Nevertheless Heraeus Kulzer recommends to use rubber dam in any case. Please bear in mind that iBOND Total Etch is an slight acidic product and unintended mucous membrane contact may result in superficial burns. This can be seen in a whitish reversible discoloration of the mucous membrane.

• The technique to be used depends on the solvent. In the case of acetone-based total-etch systems the bonding agent must be rather applied on wet, etched dentin. Water-based systems prefer drier dentin. Ethanol takes a position in the middle and is applied on moist dentin. Prior to polymerization, solvents must always be dried with air from the bonding agent. When using acetone, this is relatively simple, whereas water-based systems need to be "dried" longer. Incomplete evaporation causes deficient polymerization and failures. Summarizing these facts, we do recommend using a moist / wet bonding technique regarding the use of iBOND Total Etch

• HEMA is a hydrophilic monomer that is a good wetting agent and penetrates easily into the tooth surface. One of the drawbacks with HEMA is, that it firmly retains water in adhesives, from where it is hardly removed by air-drying. The self-etching adhesive iBOND Self Etch contains a high amount of water. Therefore iBOND Self Etch is HEMA-free and rather contains 4-META in a high amount. 4-META is hydrophilic and penetrates easily into the tooth surface too. Additionally it is acidic and responsible for the etching process.
• There is 4-META in iBOND Total Etch too but in a low amount. It functions not as wetting and acidic monomer but supports adhesion by bonding chemically to collagen fibers. Thus HEMA is necessary in iBOND Total Etch as additional wetting and penetrating ingredient. However iBOND Total Etch contains only a little amount of water so the removing of water can be achieved easily although HEMA is inside.

• iBOND Total Etch contains Glutaraldehyde. This ingredient is able to coagulate proteins and acts as desensitizing agent by plugging open tubules with coagulated proteins. Additionally it is able to bond to crosslink the collagen fiber to prevent a collapse of the collagen scaffold.

• No. The etching pattern that was created by etching enamel with phosphoric acid might be destroyed by rubbing. Subsequently the reliable bonding to enamel might be affected negatively.

• iBOND Total Etch contains ethanol and water as solvents. The total amount of solvents is approx. 40 %.
